MR. PRESIDENT,--Allow me to remind you of that famous shield suspended in the highway, and so often adduced as a lesson of candor. Two travellers approaching from opposite quarters, and standing face to face, read the inscription as each saw it. Straightway there was difference and contest. Each insisted; but closer observation showed that the two sides were different. So it is on the present occasion. The measure before the Senate has two sides. The Senator from Maine [Mr. FESSENDEN], as he approaches it, sees only the side which limits the representation. As I approach it, I see the recognition of a caste and the disfranchisement of a race. He defends it; I condemn it. But he defends only what he sees; I condemn only what I see. It is the misfortune of the measure that it has two sides with two opposite inscriptions. This is especially unhappy at this moment, when we are bound to be frank and loyal, and to do nothing which may be interpreted in a double sense. Above all should this be the case with regard to an Amendment of the Constitution. But the present proposition does not fall within these conditions. It is enough that there are at this moment two opposite opinions with regard to its meaning. Now, Sir, it will not be denied that there are opposite opinions on its meaning. The Senator from Maine affixes one meaning; I affix another. The Senator sees nothing bad; I see nothing good,--or rather, all that it proposes is absorbed, merged, and lost in the evil. Against it I am earnest, and I speak so. For those from whom I differ I have nothing but personal kindness; but I must condemn the text they seek to inject into the Constitution. What is debate? It is the expression of opinions, conclusions, and convictions. These must be expressed fully, freely, and according to the conscience of the speaker. If a measure is deemed bad, unjust, scandalous, founded in wrong principles, and calculated to produce infinite mischief, all this must be said; and it must be said with plainness, according to the nature of the exigency. To this end language is given. The measure must be exposed. There are no terms to be spared which may be needed in this exposition, whether to reach the judgment or the feelings. Of course, on this occasion I see only the subject. The Senator reminds you of the friends whose votes I arraign,--cherished colleagues in both Houses, valued associates in political opinion, and two thirds of the House of Representatives. All this increases my sorrow. It gives me a pang; but it cannot make me change convictions springing from the very depths of conscience,--nor my course.
